NCT02455648

Brief Summary

Healing of mucosal defects after endoscopic mucosal resection in the oesophagus is prone to result in varying degrees of stenosis, especially if the resected area is large and/or circumferential. A new technique was described where autologous cells from the patients own oral mucosa are harvested and cultures on proprietary membranes (coated, temperature sensitive). These membranes, coined cell sheets, are used to cover the mucosal defects.

Outcome Measures

Primary Outcomes (1)

  • Post-operative stenosis

    Development of an oesophageal stenosis that cannot be passed by a standard 9 mm endoscope

    4 weeks

Study Arms (2)

ESD/EMR plus Cell Sheet

EXPERIMENTAL

Patients receive both mucosal buccal biopsy and insertion of cell sheets during/after ESD/EMR

Procedure: ESD/EMR plus Cell Sheet

ESD/EMR

SHAM COMPARATOR

patients receive both mucosal biopsy but no placement of cell sheets during/after ESD

Procedure: ESD/EMR

Interventions

Patients receive ESD/EMR plus CellSheet: Autologous oral mucosa/buccal-derived epithelial cells, cultured on temperature-sensitive membrane ("Cell Sheet") that are inserted 2 weeks later on the occasion of the ESD or EMR

ESD/EMR plus Cell Sheet
ESD/EMRPROCEDURE

only ESD/EMR: Autologous oral mucosa/buccal-derived epithelial cells, cultured on temperature-sensitive membrane ("Cell Sheet") but NOT used for insertion in the patient during/after ESD/EMR two weeks later

ESD/EMR
